Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66508, here are decompositions:

  • 17 + 66491 = 66508
  • 41 + 66467 = 66508
  • 59 + 66449 = 66508
  • 131 + 66377 = 66508
  • 149 + 66359 = 66508
  • 269 + 66239 = 66508
  • 317 + 66191 = 66508
  • 347 + 66161 = 66508

Showing the first eight; more decompositions exist.
